There seems to be some confusion about the problem I reported, I'll
attempt to clarify.
assume three machines of signifigace on the network:
router: 205.240.209.209
rainier (offender): 205.240.209.212
any other machine :205.240.209.208/28 member
<k2:~> netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Mtu
Interface
default 205.240.209.209 UGS 1 5123 - le0
127 127.0.0.1 UGRS 0 0 - lo0
127.0.0.1 127.0.0.1 UH 2 78 - lo0
205.240.209.208 link#1 UC 0 0 - le0
205.240.209.209 0:0:93:b4:2:be UHL 1 0 - le0
205.240.209.210 0:40:5:50:4b:32 UHL 0 80 - le0
205.240.209.211 0:0:f:0:70:fb UHL 2 2622 - le0
205.240.209.213 127.0.0.1 UGHS 1 1031 - lo0
224 link#1 UCS 0 0 - le0
Encap:
Source address/netmask Port Destination address/netmask
Port Proto SA(Address/SPI/Proto)
So, clearly it would route through 205.240.209.209...
<k2:~> traceroute -g 205.238.48.1 www.infoseek.com
traceroute to guide-p.infoseek.com (204.162.96.21), 30 hops max, 48 byte
packets

ms !S
why is rainier.lart.net not minding its own business?
<k2:~> ifconfig -a
